| Abstract: | Fast-response IR detector is sensitive to vibration that come from applied environments, so the output signal of the detector is mixed of the vibration noise. A novel method for suppressing vibration noise was brought out in this paper base on digital filtering. The hardware frame and flow chart of data processing was shown base on FPGA. Digital filtering method was performed; the adaptability of the detectors in war field environments was strengthened. |
